Specification of Letters Patent.

Application filed March 1, 1915. Serial No. 11,189.

To all whom it may concern:

Be it known that I, JOHN, PnRIcrI, a subject of the King of Hungary, residing at Logan, in the county of Logan andState of est Virginia, have invented certain new and useful Improvements in Combined Door Latches and Locks, of which the following is a specification.

Thisinvention relates to certain new and useful improvements in combined door latches and locks.

An object of the invention is to provide a lock fordoors including a casing for housing the latch and operating mechanism therefor, and also a locking bolt and the operating mechanism for the same.

A further object of the invention is to provide a locking device for doors including a latch mechanism and a lock mechanism, the lock mechanism consisting of a sliding bolt controlled by sliding tumblers whereby the bolt may be heldimmovabl'e.

With the abovegeneral objects in view and others that will appear as the nature of the invention is better understood, the same con sists in the novel construction, combination and arrangement of parts'to be hereinafter more fully described and then claimed.

In the accompanying drawings which show the preferred embodiment of the present invention and to which reference is had herein by like characters designating corresponding parts throughout the several views :-Figure 1 is a vertical sectional View of a portion of a door with the present lock secured in po'sitionywith the face plate re moved and part of the elements shown in section, better to illustrate the operation. Fig. 2 is a similar view with the latch and locking bolt in retracted position, and with the tumblers elevated out of contact with the locking bolt. Fig. 3 is an end elevational view of the lock applied to a door, with a part of the door broken away showing the lock mechanism in section. Fig. 4 is a perspective view of the lock casing removed from the door. Fig. 5 is a detail perspective view of the latch. Fig. 6 is a detail perspective view of the locking bolt. Figs. 7 and 8 are detail perspective views respectively, of the latch actuator and the locking bolt actuator, and, Figs. 9 and 10 are detail perspective views respectively, of one of the sliding tumblers and the operating key for the tumblers.

Referring more in detail to the accom-- of the latch.

panying drawings, the reference numeral 15 designates a portion of a door to which the present lock is attached, there being provided the usual escutcheon plates 16 and the face plate 17, while the knobs for operating Patented Oct. 12, 1915.

the latch are designated 18 and the operating knobs for the locking bolt are designated 19. The lock casing for supporting the lock mechanism is shown includesthe face plate 17, the rear wall 20, top and bottom walls 21 and an integral. side wall 22. the open side of the casing have enlargements 23, to which a detachable side plate 2% is secured, the casing in its entirety presenting a rectangular frame. The latch mechanism includes the supporting plate 25 positioned adjacent the upper end of the casing and carries an upstanding angular flange 26 adapted to cooperate with the'rear wall 22 to provide a guide for the sliding latch 27. The latch 27 is formed with the usual beveled nose 28 and is provided with a shoulder 29 adapted to engage the rearwall of the face plate 17 to limit its out-ward movement, there being provided an opening 30 in the face plate to facilitate the passage of the nose therethrough. A pair of communicating openings are provided adjacent the rear vend of the latch 27, one extending transversely thereof as at'3l, while the other one opens from the top of the latch as at 32. In order to hold the latch normally projected through the face plate opening 30, I have provided the compression coil spring 33 guided at one end by the pin 34 carried by the rear end of the latch 27 while its other end is received over the pin, 35 carried by the rear wall 20 of The member for retracting the the casing. latch against the tension of the spring 33 comprises the latch actuator shown in detail in Fig. 7, the same being formed of rectangular end portions 36 adapted to project through alined openings 37 provided in the side walls 22 and 24 of the casing, while the middle portion thereof is formed cylindrical in cross-section as at 38, and is adapted for positioning withinthe transverse opening 31 A projecting nose 39 is carried by the central cylindrical portion 38 and projects upwardly through the opening 32 of the latch, as clearly shown in Figs. 1 to 3. hen the knobs 18 are oscillated to retract the latch 27, the nose 39 engages the rear wall 40 of in detail in Fig. 4 and- The upper and lower corners of the latch opening 32 to move the I same rearwardly against the tension of the spring 33. When the pressure is relieved, the spring will assert its force and restore the latch to its normally projectedposition.

The locking mechanism includes a locking bolt, an actuator, sliding tumblers associated directly with the bolt, and supporting means for the sliding tumblers. A pair of spaced horizontal partition walls 41 extend transversely of the casing and are provided with vertically alined series of openings 42 for the passage of the sliding tumblers 43. Three of these sliding tumblers are provided I and carry on one edge thereof adjacent the lower ends and positioned below the lower partition wall 41, projecting lugs44, the lug 44' carried by the middle tumbler being spaced slightly above the normal horizontal position of the alined lugs ofthe other two tumblers, these gaged by'thewa'rds 45 carried by the key shank46, it being noted that the middle one 'of said wards is of slightlyincreased length relative tothe other two, adapted for engaging the elevated middle lugon the central tumbler. The usual formiof key-hole opening 471s provided .in the escutcheon plates, the door and the side w'alls'of the casing to facilitate the positioning of the key 46 for, the same being shown in detail in Fig.

8 and comprises ends 52 angular in crosssection and adapted for positioningthrough alined openings 53 24 of'the casing and are adaptedto be received in the operating knobs 19 therefor.

The central portion of the locking bolt actuator 52 is formed cylindrical in cross-section as at 54, similar .to the latch actuator and this cylindrical portion supports tllGf rear end of the bolt 48, as clearly illustrated inFigs. 1 and 2. A projecting noseportion 55 is carried by the central-cylindrical portion 54, and as shown in Fig. 1 is adapted to be reoeivedin the recess 56 provided in the under face of the locking bolt 48; The rear end of the bolt 48 isprovided with a series of sockets57 into which are received Copies of this patent maybe obtained for five cents each, by addressing the lugs being adapted to be ento confine myself to the shelf mem- I "a casing, a locking in the side walls 22 and the lower ends 58 of the sliding tumblers 53,

and in such position, the bolt 48 is held in locked projected position. In order to retract the same, it is necessary that the tumblers 43 be elevated to remove the lower ends thereof from the sockets 51 whereupon the knob 19 may be rotated tocause the finger 55 to engage either of the end walls of the recess 56 in' the bolt to shift the same to retracted position.

It is to be noted that the latch is independently operated from the lock and that a single casing incloses both mechanisms while the construction of the locking bolt 48 associated with the sliding tumblers 43 is extremely simple in operation and. effective in use. The bolt 48 is retracted'in the manner as above stated after the lower ends 58 are removed from the sockets 57, such removal being caused by the locking key 46 -with the central relatively long ward '45 engaging the elevated lug 44 on the middle 'tumbler'while the shorter wards 45 engage the'lower lugs on the end tiunblers.

From the above detailed: description of the invention, it is belived that the operation will bereadily apparent, and while I have shown and described the preferred embodiment of the present invention, I do not wish the exact details of construction shown, as various forms, modifications and arrangements of the parts as shown'may'be had without departing from "the spirit and scope of the invention as claimed. a

What]: claim as new is V A device of the class described, comprising bolt slidably mounted within said casing provided with a single slot extending from side to side thereof, vertically sliding tumblers adapted to having their lower ends engaged in the single slot,

' and interlock with saidbolt and being arranged in parallelism, lugs carried by said tumblers and being arranged in dlfierent llOl'lZOIltll'PlflIlBS, and a key having wards of difierent lengths adapted to engage said I lugs to simultaneously remove the tumblers from engagement with the bolt. V

In testimony whereof I affix my signature in presence of two witnesses.
